Removing any such option was not the objective of this thread, just lifting 4K stacks from debug and making it the default. People fortunate enough to use workloads where some piece of crap code by accident works more often with the current shared 8K stacks then it does with the unshared 4K stacks can then still nicely not select it (or fix the code if possible).
